To @ZZ whom, it may concern:

Be it known that I, JOHN H. Coor, a citi# zen of the United States, anda resident of the borough of Brooklyn, city of New York, county ofKings, and State of New York, have invented certain new' and usefulImprovements in Wire-Cable Clamps, ofA which the following is aspecication, taken in connec.-

tion with the accompanying drawings, which form a art of the same.

This invention relates to clamps, and relates especially to clamps suchas may be used for connecting cables of Wire or similar material i andfor securing the ends of such cables.

In the'accompanyin drawings, illustratine an embodiment of ne invention,Figure 1 is a partial longitudinal sectional view. Fi 2 is a transversesectional view taken su stantial-lg on the line 2 2 of Fig: 1. Fig. 3represents t e two clamping members as sep arated. C

In the illustrated embodiment of this invention a plurality of taperingthreaded clam ing members are indicated as bein engaged) by a threadedsleeve Whichforces t em l together and clamps the cable between them,

a suitable thimble beingformed b the projecting thimble-arms securedltot e clampf ing'members. The two -coperatin clamping membersi and 5 shownin the ra s are: threaded externally and llare preferab y given atapering or conical' form. These 1 two clamp members are preferablygiven at one end a polygonal form 7, which may be engaged by a wrenchand may'act'as anut in rotatin the members. The two cperating faces othe'se clamp members are preferabl formed with grooves of var 'n -deptthroughout the various parts of t e c am so that Whenassembled the twoVmembers orm the curved cable-grooves, (indicated-.in Fig.

1,) the two grooves 8 and 9 preferabl curving in different directionsand, ifesired, these grooves may be formed with suitable grippingprojections or corrugations to assist 'in enga ing the cable, asisindica'ted in Fi 1.| By orming the two grooves at an ange to eachother, as is indicated in Fig. 3, their surfaces are locatedsubstantially parallel to. the taper of the clamp members, and, ur=

thermore, a loop is more readily formed in the cable in this manner atthe larger end of the members.

' The sleeve 6 is shown as provided-withthev tapering threaded `bore 12'to sup-elf die w tapering clamp members, and this "l ww. L;

be formed with the sleeve-nut indu i f mr readily rotatingthe same withrespcv fine members. In this manner avery l `Jul pressure can be exertedby the membra :fn 6a the cable inserted in the grooves by .rez .if

the combined Wedgi and screw action .l the parts of the clamp, and,furthermore the arts of the clamp may be readily and qu als," y applied.f r

Suitable thimble-arms 2 and 3 are. rigidly secured to the clam memberasolas to be in,

tegral therewith, a though the use of these.l

thimble-arms is not necessary in all cases.

As indicated, these thimble-arms 2 and 3 f 4:formed integral with theclampmembcrs ler castin or otherwise, and 5 these cooperating the endsof the thmblesarms can be forced together being limited-.by theengagement ol these square ends and shoulders.l i

In using this clamp for securing cables'in telegraph-work,for shis".rigging,`orforhoisting or other purposes t e twoclamp members l maybearranged about the. looped end of a cable which is inserted through thesleeve, the loop of-'the cable being a justed about the tbimble so "asto properly 4en age the groove therein. Then byscrewingt esleeve uponthe tapering clamp members to the desired extent the proper clampingaction is se cured byforcing thesqt'wo coperating members together 1n a",wernl manner. B

. forming tle thimble integral .with the 'clamp' members themselves amorefrigidsu port 1s iven to tlle loop of the cableandthe accidentaldisplacement of'the thimble isposi tively prevented, and,furthermoref-'thelde vice has fewer parts andcan be more-readily andcertainl assembled.' f j. y

'1. In clamps, two clamp members formed 'with a plurality of oopemtingcurved grooves extending throughout the length of the members, one endof each or' seid mem bers Aforming e mit for rotating the members,asleev'e formed with e. nut and hsving e. tepe'ring threaded bore toengage seid members Ato lforoe the seme together, each of said members'having e grooved thimbie-a-rm secured thereto, the ends of seid ermsbeing formed with tapered portions end with square ends end shouiderstosupport the ioop of e. esbe held by seid members.

2. In clamps, two tapered threaded clampn ing members formed with copereting grooves in their djacent feces and each member formed with ethimbie-erm secured thereto, the seid thimbie-arms when brought togetheredapted to form e continuous support for-'the doop of a ycebie heldbetween seid tapered members and e threaded nut to engage seid i'membersto force them together.

3, In clamps, tapered threaded clamping vmembersformed with cooperatinggrooves in ytheir adjacent faces to form n. purehty of groovessubstantially inthe piene of said edjaoent feces, en oPen-groovedtbimb1esup orwerd from seid members to support in `open ,A osition theloop of e cable and a fthree ed sieeve-to engage seid members.

4. In oemps, two Clamping members eeoh zformed with elurelityofcooperating curved grooves, lesoh seid members having e ort formed onseid members and extending,

cooperating with the curved grooves in the feces of seid camp members,the ends of seid arms being formed with square ends and shouiders to fittogether and support the ioo'p of e. eeblo held by said members. Y

5. ln clamps, tepered threaded clamping members termed-withv ooperatinggrooves in their edjecenbfeees, a threaded sleeve to engage seid membersto force them` together, and en integral grooved thimbie-arm formed oneach of seid members to support en open etteehingdoop in the eebie heldby seid members.

6. vin clamps, tapered threaded clamping members formed with cooperating`grooves in their adjacent feces, athimble-support formed on seidmembers extending,J 'forward from seid members to support the loop of eee-ble heid by seid members and e threaded seeve to engage seidmembers.'
